Expert PHP and MySQL published!
+4 Vote Up -0Vote Down

I'm very pleased to announce the publication of my book Expert PHP and MySQL, published by Wrox. This book was written by myself, Andrew Curioso and Ronald Bradford. The short of it is, upon finishing my previous book, Developing Web Applications with Apache, MySQL, memcached, and Perl, Wiley asked me if I knew of anyone who would like to write a MySQL/PHP book. I had worked with Andrew at Lycos and found him to be a brilliant PHP developer, having been the primary developer of Lycos's Webon product-- which has some excellent usage of PHP, Javascript and …

Yesterday, while at the MySQL Conference, I was interviewed by Robert Scoble about my employer, Gear6 and our product, an enterprise memcached distribution.

MySQL Conference, Day 2

While waiting in the line for a breakfast table, I found Reggie Burnett, who is still with MySQL now Oracle. We shared a table and talking about Android and the future of handhelds.

I missed the keynotes by Edward Screven and by Tim O'Reilly. Instead I had scheduled interviews with The 451 Group and then with Robert Scoble. Those both went really well. And I learned that the Screven speech went not so well, which would have been amusing, but not a good use of time.

The rest of the day, so far, has consisted …

Reacting to "Memcached is not a store"
+0 Vote Up -1Vote Down

I keep seeing "Memcached is not a key value store. It is a cache. Hence the name." This is strongly reinforced by statements made in the memcached mailing list itself.

This is short sighted.

Memcached is a number of things. It is an idea (fast key value store, with distributed hash function scaling), it is a network protocol (two of them, in fact), it is a selection of client libraries and APIs (most based on libmemcached), and it is a server implementation. In fact, now, is is now a number of server implementations, because now there are a number of different things that implement the memcached …

MySQL+Memcached is still the workhorse
+0 Vote Up -0Vote Down

(originally posted at the Gear6 corporate blog: MySQL+Memcached is still the workhorse.  Please comment there.)

Because I'm becoming known as someone who knows something about "this whole NoSQL thing", people have started asking me to take a look at some of their systems or ideas, and tell them which NoSQL technology they should use.

To be fair, it is a confusing space right now, there are a LOT of NoSQL technologies showing up, and there is a lot of buzz from the tech press, and in blogs and on twitter. …

Using ini files for PHP application settings
+0 Vote Up -0Vote Down

At dealnews we have three tiers of servers. First is our development servers, then staging and finally production. The complexity of the environment increases at each level. On a development server, everything runs on the localhost: mysql, memcached, etc. At the staging level, there is a dedicated MySQL server. In production, it gets quite wild with redundant services and two data centers.

One of the challenges of this is where and how to store the connection information for all these services. We have done several things in the past. The most common thing is to store this information in a PHP file. It may be per server or there could be one …

Active Cache for MySQL
+1 Vote Up -1Vote Down

One of the problems I have with Memcache is this cache is passive, this means it only stores cached data. This means application using Memcache has to has to special logic to handle misses from the cache, being careful updating the cache - you may have multiple data modifications happening at the same time. Finally you have to pay with increased latency constructing the items expired from the cache, while they could have been refreshed in the background. I think all of these problems could be solved with concept of active cache

The idea with Active Cache is very simple - for any data retrieval operation cache would actually know how to construct the …
